BRAKE.

Application filed August 1,' 1925. Serialv No. 47,453.

rIhis invention relates to brakes, `and is illustrated as embodied in a.y front Wheel brake for an automobile.

One feature ofthe invent-ion relates to pivoting a pair of end shoes on` a central shoe which is yanchored at one end,- thus providing a connected shoe assembly and simplifying the construction by using a single anchor for allthree slices.

Another feature of the invention contenr plates the .use of a novel and particularly strong anchor, suitable for trucks and the like, and which is lespecially easy of assembly` In one desirablearrangement, a slationary anchor part,y shown as a radiallyextending flange of* the wheel spindle, eX- tends adjacent the anchored r-shoe and is connected thereto by ananchor pin or other member which is confined in place in a novel manner by spaced parts of another shoe;

The.` above and` other featin'es of the invent-ion, including variousV novel combinations of parts and desirable particular constructions, Will be apparent from the following description of one illustrative embodiment shown in the accompanying drawings, in which:

` Fig; 1 isa vertical section through the brake, just inside the front wheel, showing the shoes in side elevation;

Fig. 2-is a section on the line 2-2 of Fig. l, showing the anchor; and

Fig. Sis a section on the line. 3-3 of Fig.' lashoiving the connection of one of the end shoes to the `central shoe.

a central. shoe 16, a reverse end shoe 18, t and a servo .end shoe 20. Each of the end `shoes 18 andZO is forked or otherwise formed at its end With spaced parallel arms 22 and 24 (Figs. 2 and 3) straddling the corresponding end of thecentral shoe 16.- The shoes are.. forced against the drum by means such as a double cam 26, against the A resistance of returnspringslQS and 30.

Each of the end shoeslS and20 is connected to shoe 16v by a pivot pin 32 passing f through aligned openings in shoe 16 and arms 22 and 24, and having a smooth head 34; slidably engaging the backing plate 12 to position the shoes laterally. v`Bushings 36,

.16 and arms 40, is conlined in place by arms 22 and 24, which block its ends. A bushing 4.4 for the opening in vslice linay be pro vided if desired.

Since the anchor pinl Ll2 and the 'pivot `pins 32 are not fastened in any Way, but

merely slipped inplace,` the abovedescribed arrangement provides ya very simple assem- Il'While one illustrative embodiment been described in detail, it is not my intention lo 'limit the scope of the invention to that particular embodiment, or otherwise j than by the terms of the appended claims.

I claim: l. A brake comprising, in combination, a

`central shoe anchored at one end, a pair of oppositely-extending end shoes connected to the central shoe adjacent its ends, and means for forcing the end shoes apart to apply the brake. L i

Q. A'bralte comprising, `in combination, a central shoe pivotally anchored 'at one end,

' a pair jof `,oppositely-extending end shoes vpivoted tothe central shoe adjacent its ends,

and means for forcing thevend shoes apart to applythe brake.'

In thevillustrated brake, the shoes or their eqnivalentsare arranged between 4a drum l0 and a backing plate 12 carried by 'the'. Wheel spindle 14'. Three shoes are shown,n 2

A lbrake comprising, in combination, a central `shoe anchored at `one end, a servo shoe connected to the unanchored end of the central shoe and arranged lto `operate the central shoe, a third shoe connected to the central shoe its anchored "end, and inea-ns for forcing the servo 'shoe and the third shoe apartr to` apply the brake. Y Y j i ab A brake comprising, in combination, av first shoe anchored at one end, another shoe forked to straddle the anchored end of the lirst sho-e and having its forked end pivoted to the first shoe, and means for forcing the shoes outwardly to apply the brake.

j 5. A brakecOmprising, in combination, a lirst `shoe andan adjacent stationary part, an anchor member connecting the shoe and said part, and a second shoehaving spaced portions straddling thelirst shoe and said part and confining the anchor member in place.

6. A brake comprising, in combination, a iirst shoe and an adjacent stationary part, an anchor member connecting the shoe and said part, a second shoe having spaced portions straddling the first shoe and said part and confining the anchor member in place, and a connection between the second shoe and the iirst shoe.

7. A brake comprising, in combination, a lirst shoe and an adjacent stationary part, an anchor member connecting` the shoe and said part, and a second shoe having a part overlapping the lirst shoe and confining the anchor member in place.

8. A brake comprising, in combination, a lstationary part forked at one end to form a pair ot spaced arms, a brake shoe eX- tending between said arms, an anchor member connerting the shoe and said arms, and means separate 'from said shoe and disconnected from said member and arranged at the ends of said anchor member to confine it laterally.

9. A brake comprising, in combination, a stationary part forked at one end to form a pair ot spaced arms, a brake shoe extending between said arms, an anchor member connecting the shoe and said arms, and a member having spaced portions straddling the arms and shoe and confining Vthe anchor member in place.

`10. A brake comprising, in combination, a stationary part having a pair of arms, a brake shoe having a part extending between said arms, an anchor member connecting the shoe and arms, and a second brake shoe having spaced portions coniining the anchor member in place.

11. A brake comprising,in combination, a stationary7 part having a pair of arms, a brake shoe having a part extending between said arms, an anchor member connecting the shoe and arms, a second brake shoe having spaced portions confining the anchor member in place, and means for anchoring the second shoe between the ends of the first shoe.

12. A brake comprising, in combination,

a stationary part, a brake shoe, an axially floating anchor member connectingl the part and shoe, and a second shoe having portions confining the anchor member in place.

18. A brake comprising, in combination, a stationary part, a brake shoe, an axially floating anchor member connecting the part and shoe, and a second shoe anchored between the ends o'l the firstshoe andhaving portions confining the anchor member in' place. Y

14. A brake comprising, in combination, a stationary pair of anchor arms, a brake shoelextending between said arms, an anchor pin extending through aligned openings in the shoe and arms, and a second shoe having spaced parts blocking the ends of the anchor pin.

15. A brake comprising, in combination, a stationary anchor part, a brake shoe extending adjacent said part, an anchor pin extending through aligned openings in the shoe and part, and a second shoe having spaced parts blocking the ends of the anchor pin.

A brake comprising, .in combination, a spindle having a radially-extending anchor arm, a brake shoe, an anchor pin passing through the arm and shoe, and a` second shoe anchored between the ends of the first shoe and having spaced parts straddling said arm and the anchored part of the lirst shoe and blocking the ends of the anchor pin.

18. A three-shoe 'brake comprising, in combination, a central shoe, a pair oi' end shoes connected to opposite ends of the central shoe and having arms straddling the ends or the central shoe, a stationary part having ari'ns extending between the arms of one end shoe and straddling the end of the central shoe, and an anchor member connecting the central shoe and the arms of the stationary part.
